Hanzi (Kanji) characters for digits 0-9 are: 〇, 一, 二, 三, 四, 五, 六, 七, 八, 九 with html character entities resp. 〇, 一, 二, 三, 四, 五, 六, 七, 八, 九. 零 零 is also used for number zero.
The hexadecimal values are 3007, 4E00, 4E8C, 4E09, 56DB, 4E94, 516D, 4E03, 516B, 4E5D.
From Alonso del Arte, Oct 20 2019: (Start)
The characters indexed by these code points are more like words than digits, sort of like the difference between the word "three" and the character "3".
With one exception, all of these characters come from the CJK Unified Ideographs block, into which they are sorted according to stroke count or stroke count of the primary radical rather than the numerical value of the number word.
Only the zero character has an associated numeric value that can be accessed through Java's Character.getNumericValue() function. The rest return -1 to indicate "the character does not have a numeric value." (End)

Examples

			The very first character of the CJK Unified Ideographs block is 一 U+4E00 (19968), which means "one". It is followed by two characters not having numeric meaning, and then the next is 七 U+4E03 (19971), which means "seven".

This order of runes with these graphic forms is used in many rune staves in the collections of the National Museum of Finland. Note that the first sixteen of them make up the so-called younger futhark (runic alphabet), but with the fourteenth and fifteenth runes (codes 5850 and 5848, i.e. ᛚ ᛚ (L) ᛘ ᛘ (M)) having swapped their places from the usual m-l order:
ᚠ (F), ᚢ (U), ᚦ (Th), ᚭ (O), ᚱ (R), ᚴ (K), ᚼ (H), ᚿ (N), ᛁ (I), ᛆ (A), ᛋ (S), ᛏ (T), ᛒ (B), ᛚ (L), ᛘ (M), ᛦ (Y); or, using html character entities:
ᚠ (F), ᚢ (U), ᚦ (Th), ᚭ (O), ᚱ (R), ᚴ (K), ᚼ (H), ᚿ (N),
ᛁ (I), ᛆ (A), ᛋ (S), ᛏ (T), ᛒ (B), ᛚ (L), ᛘ (M), ᛦ (Y).
The last three lunation runes were ligatures, coined to make up the full 1-19 set: ᛮ ᛮ (ARLAUG), ᛯ ᛯ (TVIMADUR), ᛰ ᛰ (BELGTHOR).
